The system displays wind as True Wind or Relative Wind (see picture below).
Unit of wind can be selected either m/s or Kt.
The common understanding of wind modes is: The wind as measured by wind meter is known as apparent wind. If
indicated wind includes speed compensation it is known as relative wind. If indicated wind includes both speed and
heading compensation it is known as true wind,
Below is an example where wind speed and direction is shown both True and Relative Wind presentation.
